Case Histories

Asbestos Abatement

Wells Fargo Tower - Portland, OR

Challenge:

Safely stabilize, seal, and protect asbestos containing fireproofing, without disturbing asbestos fibers.

Solution:

A SAFE Encasement System using SE-110 and SE-120 was used to stabilize and seal the existing hazardous fireproofing material, while providing Wells Fargo with a 20-Year Limited Warranty.

Univ. of Minnesota (room)

Challenge:

The exposed ceiling in a prominent storage area was coated with fireproofing that contained asbestos fibers. This area was scheduled for future renovation and the client had concerns about how well encased fireproofing would accommodate these plans. Unique to this situation was the fact that there also existed a coating of Lead-Based Paint (LBP) that had been applied over portions of the Asbestos Containing Material (ACM) fireproofing.

Solution:

The licensed ACM workers at the University of Minnesota installed the SAFE Encasement System. They first applied SE-110 Penetrating-Stabilizer (primer) that was air-less spray applied at 16-20 wet mils thickness. The primer was allowed to dry overnight, then 18-20 wet mils of SE-120 Protective-Skin was applied over the dried SE-110. The final encasement system cured to a total thickness of over 18 dry mils, with much of the primer penetrating the LBP and ACM fireproofing.

Univ. of Minnesota (bldg.)

Challenge:

The paint on the exterior of a University of Minnesota building with several thousand square feet of corrugated steel siding was in badly deteriorated condition. Normal sampling for Lead-Based Paint turned up negative, but to their surprise, the paint was an Asbestos Containing Material (ACM).

Solution:

Surface preparation consisted of wet wiping the areas with extremely loose paint or excessive dirt. SE-110-CI Penetrating-Stabilizer (primer with Corrosion Inhibitors) was spray applied directly over the deteriorated paint at 10-12 wet mils and allowed to dry overnight. SE-110-CI penetrates this brittle surface and dries to a clear tacky flexible film. SE-120 Protective-Skin was spray applied at 10-12 wet mils. Use of this SAFE Encasement System safely mitigates the hazardous, chalky, brittle properties of the deteriorated paint.

Office Building - Los Angeles, CA

Challenge:

The building owner had a tight schedule for accommodating the move in needs for his tenant, which included the installation of fiber optics, data lines and custom power distribution above the old lay-in ceiling. Removal and replacement of the asbestos containing fireproofing required a more extensive tear out of existing lights and walls with a costly price and lengthy schedule that did not meet the new tenant’s schedule or the owner’s budget.

Solution:

The owner chose to encase the fireproofing, which only required the removal of the lay-in ceiling system. Working under full containment and with limited demolition, the contractor first spray applied SE-110 Penetrating-Stabilizer over all the exposed ACM. This was allowed to dry, and then the stabilized surfaces were over-coated with SE-120 Protective-Skin top-coat. Within 2 weeks of starting this abatement project, other trades were allowed to enter the finished areas to begin their work without the risk of disturbing ACM. The remodeling was completed in a timely manner and the use of encasement shortened the move-in schedule by 3 months, while saving the building owner over $500,000.00.
